"walk the plank." your captain says before your crew throws you off the ship. your arms and legs tied to each other, you can't swim. you start to lose your breath, your vision goes blurry. you see a shape come up to you, you feel pressure on your lips before you pass out. you wake up in a kelp bed, with the fins, tail and gills of a merperson you look around and see another merperson. "oh, you're up. finally. my names Katsuki Bakugou. I saved your sorry ass, so be grateful." he says.
